Applied circuit

Chip peripheral circuit and sensor

Control voltage of the display and relay

The AC input voltage will be stepped down by the transformer and be converted into the DC voltage by the rectifying circuit (D101-104). The 1000F/35V wave filter capacitor will be used to filter out the residue AC voltage and the manostat 7812 is used to output the steady 12V DC voltage that will be used as the control voltage of the relay and display. The 12V DC voltage will be regulated by the manostat 7805 to output the steady 5V voltage, which will be used as the output voltage of the chip peripheral circuit and various signals (sensor, switch) .

6-2 Reset Circuit Part

The reset circuit part enables the system program to return the system that meets power trouble

or abrupt power-off to the initial state by the memory of the core chip. At the very beginning of

the power-on, the reset chip voltage is LV, and becomes HV after normal operation.
